If I could time travel, I would go back to June 2019 so I can spend more time with my mom, she passed away less than a month ago and while I saw her a lot of times, we never spent quality time together, not unless we go shopping. I wish I can just go back and show her how much she means to me and thank her for being the best mom taking care of me. Edit:Thank you, all of you for the kind words, I really appreciate it.

I’m here because I lost my son of 17 years old due to suicide on September 23, 2019. On my desperate moment in agony I cry and ask myself how can I go back in time and not leave house that morning and stay home with him.

my personal theory is that if you want to travel to yesterday and meet yourself, then yesterday you should've met the you that came from the future, only if you travel in the same universe.(i'm no scientist but i love this kinda stuff)

If we could ask a dog what time it was... He may reply, "It's now, it is always now"

If I can reset my whole life and fix every mistake ever made, I'd be genuinely happy for once.

The answer is: "yes" - clicking on this video instantly transported me back 2 years in time.

I like his argument. It's what I have been saying for a very long time. Ancient Greeks might have thought you cannot fly, yet here we are hopping from continent to continent. They certainly would not have perceived a rocket leaving earth and venturing into the vacuum. Those assertions were based on existing science at the time. Our assertions are limited by what we understand now.

Time travel into the future is definitely possible. You're doing it now!

Now I understand why Flash needed to run in a circle to jump through the wormhole to travel back in time. He was spinning around the cylinder. And it makes sense why Reverse Flash created the Tachyon Device. It all makes so much sense now. This became my favorite TedTalk yet. 😭🙏🏽

it's POSSIBLE, you'll just be on your 'new parallel altered universe', or your 'new present universe' when you go back; but you'll be gone forever on your 'real previous universe'.

If time travel evers exists in the future, then it will have always existed..

AM I THE ONLY ONE THAT WANTS TO GO BACK TO THE PAST TO 2002 TO WATCH SPIDER-MAN IN THEATERS AND 1978 TO WATCH HALLOWEEN IN THEATERS

We need to focus more on time travel to the past and create a timeline where the problems on earth didn’t happen
